Can you teach an 'old' guy new style?

I've talked before about how guys don't 'get' fashion. This is particularly true in my workplace. I work for a manufacturing company and the guys there feel the same about fashion as I do about the knowing the inner workings of a car engine; couldn't give a rats and think even less of those that do. For example, at our last Christmas party, the invite said smart casual. The executive assistant who had planned it was wearing a LBD, a sparkly pink cardigan and heels. The factory guys were wearing stained boardshorts and ripped t-shirts, and not in a 'I'm a rocker, its on purpose' way. We were lucky they had gone home to shower first (and I'm not even too sure about that!).
